Title: A rotary internal combustion engine
IPC: F02B53/00
Filed: 1961-02-07
Abstract: 947,812. Rotary piston internal combustion engines. A BERGERETTO. Feb. 7, 1961 [March 16, 1960; Dec. 28, 1960], No. 4474/61. Heading F1F. A rotary piston I.C. engine comprises an engine body CM, Fig. 1, having a substantially spherical chamber in which rotate blades A, B, C, D mounted in diametrically opposite pairs AB, CD, Fig. 3, on coaxial shafts and coupled together by slotted levers L-AB, L-CD, Fig. 6, one fixed to each shaft, and rollers E co-operating with the lever slots and with a guide channel Cg in each side plate Ps between which the levers are disposed. In Fig. 3, the blades are shown at the commencement of a cycle with the compressed gases between the blades D and B being ignited by a spark plug Ca. On ignition the blade B is rotated clockwise and through the lever L-AB, the blade A. Anti-clockwise rotation of the blade D is prevented by wheel RL and a ratchet. Simultaneously with expansion between the blades D and B, spent gases are expelled ahead of the blade B through an exhaust port Fs, the blade A sucks in gas mixture through a port Fa, and gases from a previous cycle are compressed between the blades AD. During this time the lever L-AB moves from its Fig. 6 position to the position shown in Fig. 7, the rollers E being carried along the slots Sl in the lever L-CD. The lever L-CD and hence the blades C, D remaining stationary whilst the engine output shaft AA, by means of a lever AM and due to the inclination of the slots Sl moves through an angle of 55 degrees and the blades A and B move to positions slightly spaced from blades D and C respectively. A flywheel VM secured to the engine shaft then further moves the lever L-AB and through the rollers E, also the lever L-CD, so that the engine shaft moves through a passive phase of 35 degrees with all the blades moving together. The blades A, D occupying the positions previously occupied by the blades D, B. Ignition of the gases between the blades A and D then takes place and another active phase of the engine rotates the engine shaft through a further 55 degrees. Thus on one complete revolution of the engine shaft each blade is acted on in turn to rotate the engine shaft through 55 degrees and between each active phase the flywheel rotates the engine shaft through 35 degrees. In a modified construction, the engine body CM is cylindrical and differential bevel and planet gearing is included to rotate the engine shaft AA.
